class{'someclass::package': }
-> class('someclass::configure':}
-> Class["someclass"] # or -> Class[$name]
Is the correct version of this. It's a "soft" version of the anchor pattern,
because:
package{"foo": require => Class["someclass"]}
will have the inner classes completed before it without any crazy extra
resources and stuff and it handles the case most people actually care for - but
this is not a full contained class like contain() makes, you should probably
use contain() today.
